| Abstract | In order to move more people in fewer vehicles with limited capital investment, priorities for High Occupancy Vehicles (HOV) have been developed and implemented over the past several years. This study focuses on one of the options of HOV: non-separated concurrent-flow high occupancy freeway lanes. One freeway lane with an average occupancy of 1.3 persons per car can carry 2600 persons per hour. When the occupancy is increased to 4 persons, the hourly person rises to 8000. However, the idealized outcomes have not been realized by reserved lane projects. Through a comparative analysis of results of the three most recent concurrent-flow projects: the Southeast Expressway in Boston, I-95 in Miami, and the Santa Monica Freeway in Los Angeles, this paper attempts to develop a better understanding of the issues that surround the reserved lane concept. These sites were chosen because they represent recent experiments with the concept and because of their substantial differences. The issues addressed in this report are: (1) changes in travel times on the freeways and in transit level of service; (2) modal shift to carpooling and transit; (3) capital and operating costs; (4) changes in accidents and incidents, violation rates, and enforcement; (5) the public's attitude towards the reserved lane concept, the effect of advertising and media, and the role of politics; and (6) the design and operating environment appropriate to the concept. The three projects met with differing degrees of success and failure, and those in Boston and Los Angeles have been terminated. Carpooling increased by about 70 percent and travel times for those using the lanes decreased. There were several weaknesses in the concept, which are discussed in the report. The study presents recommendations for future HOV priority projects. A Listing of References is contained herein. /UMTA/ |
